What you got is called inequality .You need to find the values of variable x that make the inequality true. Hence
Move -30 to other side and change sign.
Move -3x to other side and change sign as well
Now add in both sides
Divide by 7 both sides
Hence the values of x that satisfy the inequality belong to interval
